A customer wants to integrate a Dell EMC Unity Hybrid system with a Linux OS host running on Oracle application. The Oracle application requires that the database files are deployed on a large amount of spindles to meet a low I/O latency requirement. In addition, the customer wants to use the available Unity drives and deploy the database on 10K RPM SAS or NL-SAS, reducing the number of required spindles. Which Unity feature will enable the proposed solution to provide effective storage utilization and optimized performance?

A. Dynamic Pools

B. FAST Cache

C. Traditional Pools

D. FAST VP
